To all whom it may concern:

Be it known that I, HERMAN R. MOHRMAN, a citizen of the United States, residing at Dell Rapids, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Combined Pullers and Presses, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to combined puller and press and has for an important object the provision of a tool capable of multiple use in garages and service stations, being particularly adapted for the removal of wheels, gears and the like from their mountings.

An important object of the invention is to provide a device of this character which is capable of engagement with a wheeleither against the spokes thereof or by attachment to the hub bolts of the wheel.

A further object of the invention is to provide a device of this character which may be employed for removing from wheels of the full floating type the axle housing upon which they are mounted.

A further object of the invention is to provide a device of this character which is caable of use as a press.

Other objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout,

Figure 1 is a perspective View showing one manner of applying my device for removing a wheel from the mounting thereof;

Figure 2 is a side elevation partially in section showing my device employed for removing a gear from a shaft;

Figure 3 is a sectional view partially in elevation showing my device employed for removing a wheel having a full floating axle from its mounting, and showing a dif ferent manner of applying the device to the wheel;

Figure 4 is a section on the line 4-4 of Figure 3, and

Figure 5 is a side elevation partially in section showing my device mounted for use as a press.

Referring now more particularly to the drawings, the numeral 10 indicates the central portion of a spider, and the numeral 11 the arms thereof, which are preferably poly onal in cross section. The central portion 10 of the spider is provided with a screwthreaded bore 12, the purpose of which will hereinafter appear.

The numeral 13 indicates puller arms having at their lower ends arcuately curved feet 14 of greater width than the arms and having the excess width of the foot disposed at the inner face of the arm, ,as indicated at 145*, to provide a shoulder. The feet'l l have formed therein pairs of arcuately extending slots 15. The upper ends of the puller arms 13 are provided with heads 16, embodying central openings adapted for the slidable reception of the arms 11 of the spider and may be held in adjusted position thereon by means of set screws 16? or the like.

The numeral 17 designates a threaded bar adapted to extend through the threaded opening 12 of the spider center 10. The upper end of the bar 17 may be polygonal in form for coaction with a similarly shaped opening formed centrally in a handle member 19, and the lower end of the bar is provided with a spur point 20. This spur point is adapted to coact-with the usual countersink or centering bore usually formed in the ends of shafts.

1n the use of my device for removing the wheel W from the mounting thereof, the pullerarms 13 may be extended through the spokes S of the wheel so that the feet 14 thereof engage against the opposite side of the wheel from the spider member, and the arms adjusted inwardly upon the spider member to bring these feet as closely together as possible, which in the majority of wheel structures at present in use will be when the inward movement of the feet is prevented by their engagement one with the other, so that the feet form practically a continuous circle behind the spokes of the wheel, giving an even strain all around the wheel. If desired, the feet 14 may be secured to the wheel by removing the nuts from the bolts 21 usually holding the hub plate in position and permitting these bolts to extend through the slots 15 of the feet lt, when the nuts may be replaced to hold the feet against movement. When the feet have been arranged in the proper position the shaft 17 may be screwed through to engage the end of the axle A of the wheel.

In wheels of the full floating type and wherein the axle A does not form the means of attachment for the wheel, but where the videdwith a countersunk socket 24 adapted for the reception of the spur 20 of the shaft 17. When it is desired to employ the device for removing a solid member from a shaft, as for example a gear Wheel, this may be accomplished by moving the puller members 13 inwardly until they engage against the periphery of the gear G at which time the shoulders 149 of feet 14: will be engaged behind the gear so that the gear may be'removed by moving the shaft 17 inwardly.

My device may be readily employed as a press by securing the feet 14 of the puller members upon a table or support 25, the

table or support having formed therein an opening 26 alining with the shaft 17. It will be obvious that when it is desired to remove a bushing from a gear, pulley or the like, the same may be arranged upon the table 25 and the bushing removed by employing a thrust member similar to that above described. When mounted upon the table 25, the device is, as will be readily obvious, capable of general use as a press, and where some detachable fastening such as is disclosed is employed, the devlce may be readily removed at any time it is desired to employ it at a point remote from the table.

From the foregoing it is believed to be obvious that a garage tool constructed in accordance with my invention is particularly well adapted for use by reason of. the wide range of uses to which the same may be put, and by reason of the simplicity of the const-ruction thereof. It will furthermore be obvious that the construction of the same as hereinbefore set forth is capable of some change in modification Without materially departing from the spirit of my invention, and I accordingly do not limit myself to the specific structure hereinbefore set forth except as hereinafter claimed.

What I claim is:

' 1. In a tool of ,the character described, a spider member embodying a plurality of radial, arms, puller members adjustably mounted upon said arms, flat arcuate'feet'secured at their longitudinal centers to the free ends of the arms, the curvature of-said feet having as an axis a point substantially central of the spider member, and a shaft having threaded engagement with the spider member at the central portion thereof.

2. In a tool of thecharacter described, a spider member embodying a plurality of radial arms, puller members adjustably mounted upon said arms, fiat arcuate feet secured at their longitudinal centers to the free ends of the arms, the curvature of said feet having as an-axis'a point substantially central of the spider member, and a .shafthaving threaded engagement with the spider member at the central portion thereof, said feet being of greater width than said puller members and having theexcess width thereof disposed at the inner face of the puller members whereby toprovide a shoulder.

3. In a tool of the character described, a spider member embodyinga plurality of-radial arms, puller members adjustably mounted upon said arms, flat arcuate feet secured at their longitudinal centers to the free ends of the arms, the curvature of saidfeet having as an axis a point substantially central of the spider member,- and ashaft having threaded engagement with the-spider member at the central portionthereof, said feet having formed therein arcuate slots co-directional with the feet. p

In testimony whereof I- hereunto aflix my signature.
